Specification of Letters Patent.

Patented Oct. 29, 1907.

Application filed March 2. 1907- Serial No. 360.202.

To all whom it may concern:

Be it known that I, THOMAS T. HOSACK, a citizen of the United States, residing at Oil City, in the county of Venango and State of Pennsylvania, have invented a new and useful Solder for Aluminum, of which the following is a specification.

This invention relates to means for soldering aluminum, either aluminum parts together or aluminum to other metals.

The primary object is to provide an effective, non

oxidable solder composed of inexpensive ingredients that can be melted together in practically any character of melting pot or crucible over any fire of sufficient aluminum ware or can ,be used in securing together aluminum and other metal, as experience has demon- 'strated that other metals can be tinned with the solder and the parts joined together. Moreover, an ordinary soldering iron can be employed and no flux or cleaning agent has been found necessary. Experience has demonstrated that the solder will notoxidize and that the same is very strong and tenacious, parts soldered together therewith having stood a test of fifteen hundred pounds to the square inch without pulling apart.

What I claim, is:- $5

1. A solder of the character set forth, consisting exciusively of block-tin, antimony, and aluminum.

2. A solder of the character set forth. consisting oi substantially two-thirds hlock-tin, one-sixth antimony and onesixth aluminum. 4()

In testimony. that I claim the foregoing as my own, i have hereto affixed my signature in the presence of two witnesses.

THOMAS 'r. IIOSACK.
